My thoughts exactly. What I was going to say is that it's harder to get up on that white path from the ground. Blue attacking wise nothing's changed, but Red defense wise has.
In order to get into that building from the point A side and head towards Blue spawn you have to make...6 jumps. That's no longer a path, that's a wall.
And yes, looks like there's a new path just above that top box. Though I think that's less of a gameplay change (it goes essentially the same place as the door).
